Do you buy any food at all that is not grown by local organic farmers? If you do, chances are you have a much stronger business relationship with Monsanto than Paul Graham does. After all, you are directly giving money to a supermarket, which is giving it to a big agribusiness, which either is Monsanto or is a customer of Monsanto. All these evil things that Monsanto does? They're done with your money. Contrast that…
Is it that evil is efficient or that being "good" (providing positive externalities in the process of delivering goods/services) is less efficient?
I'd agree more with your second phrasing, as it's more nuanced, but they seem to be getting the same general idea across.
